| 설명 | 청신경(제8뇌신경)의 신경겉을 싸고 있는 집(sheath)의 슈반세포(Schwann cell)에서 기원하는 종양-뇌종양 중 비교적 흔하며 대개 40~50대에 호발한다. 증상으로는 귀울림, 난청, 소뇌기능장애 등이 있으며, 이중 귀울림이 가장 초기의 증상이다. |

|---|---|---|---|
| 설명 | 전신의 여러곳에 무더기로 나는 신경섬유종을 특징으로 하는 유전성 전신 병. 말초 신경뿐 아니라 중추 신경계도 침범할 수 있다. 신경섬유종은 주로 전신의 피부에 발생되지만 신경얼기 혹은 내장에 생기는 수도 있다. 피부에는 또한 곳곳에 특유의 갈색색소반을 보게 된다. 골격의 변형을 일으킬 수도 있다. 신경초종이나 악성신경초종, 더욱이 신경교종이나 수막종 등의 두개내종양을 합병함도 알려져 있다. 1형(von Recklinghausen 병, 전형적 신경섬유종증)과 2형(중추형 또는 청각신경섬유종증)으로 구분한다. 전형적 신경섬유종증(1형)이 가장 많이 발생하며 다음과 같은 3가지 소견을 보인댜. 즉 ① 체표면, 체내 여러 곳에 산재되어 발생하는 얼기모양신경종, ② 우유커피반점, ③ 리쉬(Lisch) 결절로 불리는 홍채의 착색과오종이다. 2형은 1형보다 발생빈도가 적고, 특징적으로 양쪽성 청각신경종이 있으며, 우유반점은 보이나 리쉬결절은 없다. |

Incomplete neurofibromatosis, multiple neurofibromas with minimal manifestations, perhaps limited to cafe-au-lait spots; individuals with minimal lesions may have offspring with severe involvement. Synonym: abortive neurofibromatosis. (05 Mar 2000) |
| neurofibromatosis | <oncology> One of the most common disorders in genetics, neurofibromatosis encompasses at least two diseases, designated NF-1 and NF-2. NF-1 or classic neurofibromatosis, is characterised by the familiar cafe- au-lait spots, axillary freckling, cutaneous and visceral neurofibromas (which sometimes undergo malignant transformation), gliomas, scoliosis, and Lisch nodules of the iris. NF-1 is associated with the the von Recklinghausen Neurofibromatosis locus that encodes the NF-1 protein, a GTPase activating protein which interacts with the ras proteins. The gene is located on chromosome 17. NF-2, also called acoustic or central neurofibromatosis, features neurofibromas restricted to the acoustic nerve (usually bilateral) and the central nervous system, skin lesions may or may not be present. The gene is located on chromosome 22. There are no biochemical markers of the disorder, but the cloning of both the NF-1 and NF-2 genes makes DNA-based diagnosis possible in some families. Both genes appear to be tumour suppressor genes. Both conditions are autosomal dominant, but the variable penetrance and expressivity and high frequency of new mutations make genetic counseling difficult. Inheritance: autosomal dominant. (29 Dec 1997) |
| neurofibromatosis 1 | A congenital autosomal dominant disorder characterised by developmental changes in the nervous system, muscles, bones, and skin especially in those derived from the embryonic neural crest. There are multiple cutaneous tumours and tumours of the peripheral and central nervous system. The disease has been linked to mutations of the nf1 gene on chromosome 17. (12 Dec 1998) |
| neurofibromatosis 2 | Severe autosomal dominant disorder characterised especially by bilateral acoustic neuromas as well as other multiple tumours including meningiomas, ependymomas, spinal neurofibromas, and gliomas. The disease has been linked to mutations of the nf2 gene on chromosome 22. (12 Dec 1998) |
| acoustic | Pertaining to the sense of hearing, the organs of hearing, or the science of sounds; auditory. Acoustic duct, the auditory duct, or external passage of the ear. Acoustic telegraph, a telegraph making audible signals; a telephone. Acoustic vessels, brazen tubes or vessels, shaped like a bell, used in ancient theaters to propel the voices of the actors, so as to render them audible to a great distance. Origin: F. Acoustique, Gr. Relating to hearing, fr. To hear. A medicine or agent to assist hearing. Source: Websters Dictionary (01 Mar 1998) |
| acoustic agraphia | The inability to write from dictation. (05 Mar 2000) |
| acoustic aphasia | An impairment in comprehension of the auditory forms of language and communication, including the ability to write from dictation in the presence of normal hearing. Spontaneous speech, reading, and writing are not affected. Synonym: acoustic aphasia, word deafness. (05 Mar 2000) |
| acoustic area | The floor of the lateral recess of the fourth ventricle, extending medially to the limiting sulcus and overlying the cochlear and vestibular nuclei of the rhombencephalon. Synonym: area acustica. (05 Mar 2000) |
| acoustic cell | A hair cell of the organ of Corti. (05 Mar 2000) |
| acoustic crest | An elevation on the inner surface of the ampulla of each saemicircular duct; filaments of the vestibular nerve pass through the crista to reach hair cells on its surface; the hair cells are capped by the cupula, a gelatinous protein-polysaccharide mass. Synonym: crista ampullaris, acoustic crest, transverse septum. (05 Mar 2000) |
| acoustic enhancement | A manifestation of increased acoustic signal amplitude returning from regions beyond an object which causes little or no attenuation of the sound beam. Compare: acoustic shadow. (05 Mar 2000) |
| acoustic impedance | The resistance that a material offers to the passage of a sound wave (colloquial); a property of a medium computed as the product of density and sound propagation speed (characteristic acoustic impedance). Discontinuities in acoustic impedance are responsible for the echoes on which ultrasound imaging is based. Unit: the rayl. (05 Mar 2000) |
